List for the first three major caliphates, which cover the period from the death of the Prophet Muhammad up to the Mongol sack of Baghdad, followed by other major autonomous or semi-autonomous dysnasties.

The dates are given in Anno Hegirae (AH/H), followed by the corresponding Common Era (CE) dates.

(AH 11–40 / CE 632–661)

II. Umayyad Caliphate (Damascus) #

(AH 41–132 / CE 661–750)

III. Abbasid Caliphate (Baghdad) #

Ottoman Sultanate (Empire) #

The most significant sultans from the major periods of the empire’s history is listed below, along with their accession and end dates in both AH (Anno Hegirae) and CE (Common Era).

Rustumid Imamate #

The Rustumid Imamate (also spelled Rustamid) was an Ibadi state centered in Tahert (near modern Tiaret, Algeria) that existed in the central Maghrib from the late 8th to the early 10th century. Here is a list of the Rustumid Imams with their approximate accession and end dates in both AH (Anno Hegirae) and CE (Common Era).

Fatimid Imamo-Caliphates #

The Fatimid Caliphate was a Shia Isma’ili dynasty that ruled over a vast empire in North Africa, Egypt, and parts of the Levant and Arabia from the 10th to the 12th century CE. The Fatimid rulers held the dual titles of Caliph (political head) and Imam (spiritual head of the Isma’ili branch of Shi’a Islam).

The dynasty was founded in Ifriqiya (modern-day Tunisia and eastern Algeria) in 909 CE (297 AH) and later established its capital in Cairo (al-Qahira), founded in 969 CE (358 AH). The caliphate was abolished by Saladin in 1171 CE (567 AH).

Twelver Imamates #

There has never been a historically recognized Twelver (or Imami) Caliphate in the same continuous, institutional sense as the Sunni Caliphates (Rashidun, Umayyad, Abbasid, Ottoman).

The modern Islamic Republic of Iran, a Twelver state, is led by a Supreme Leader (a Marja’ al-Taqlid or Grand Ayatollah) based on the doctrine of Guardianship of the Jurist (Wilayat al-Faqih). This is a system of governance by qualified scholars during the Occultation, and while it exercises supreme political and religious authority, it is not referred to as a “Caliphate.”

Historically, while Twelver Shi’a was the official religion of powerful states, these states did not generally claim the title of “Caliphate”:

The Safavid Empire (1501–1736): The most significant Twelver state was the Safavid dynasty in Persia (Iran). Shah Ismail I made Twelver Shi’ism the official state religion. The Safavid rulers used the title Shah (King or Emperor), and while they claimed spiritual descent from the Imams and their political authority was religiously based, their official claim was not the Caliphate but the Imamate’s temporal representation or simply a divinely sanctioned monarchy. They did not claim to be the Caliph (successor to the Prophet) in the traditional sense, especially during the Occultation.

Zaydi Imamates #

The other major Shia group, Zaydis, did establish autonomous rule similar to the Ibadis of north Africa.

The Zaydi school successfully established two major, long-lasting polities:

1. The Zaydi Imamate of Yemen (897–1962 CE) #

Establishment: Founded in 897 CE by al-Hadi ila’l-Haqq Yahya, a descendant of Hasan, in Sa’da (northern Yemen).

Duration: This Imamate endured, off and on, for over a thousand years, making it one of the longest-lived Zaydi states in history.

Significance: It was a continuous political and religious authority, often ruling large parts of the Yemen highlands until its overthrow in the 1962 revolution.

2. The Zaydi Imamate of Tabaristan (Caspian Sea Region) (864–928 CE) #

Establishment: Established by al-Hasan ibn Zayd in the mountainous region south of the Caspian Sea (modern-day Iran).

Significance: This was the first major Zaydi state. Although it was short-lived (being overthrown by the Samanids), it played a crucial role in the spread of Zaydi thought.

So, while Zaydi rulers never adopted the title of Caliph (which was primarily used by the Sunni Abbasids, the Isma’ili Fatimids, and later the Ottomans), they did establish a political and religious structure of their own, called the Imamate, which functioned as a governing state ruled by an Imam.
